Source coupled differential complementary colpitts oscillator

摘要

A source coupled differential complementary Colpitts oscillator is described, which enables a differential oscillation and also can improve phase noise performance by source-coupling a complementary Colpitts oscillator using an inductor. A differential complementary Colpitts oscillator includes: a plurality of complementary Colpitts oscillators and a source coupler which couples a source node of the plurality of complementary Colpitts oscillators, enables the Colpitts oscillators to differentially oscillate.
